(SEYMOUR) - A fire sprinkler line broke at the Jackson Superior Court Building, gushing perhaps thousands of gallons into the structure on Thursday afternoon.

Firefighters turned off a sprinkler riser, stopping the flow of water, Seymour Fire Chief Brad Lucas said. He said his assumption is that line had been frozen because of the recent frigid temperatures.

But not before about three-quarters of an inch of water covered the north half of the building, including the chambers of Jackson Superior Court Judge Bruce Markel and the courtroom.
